{mosimage}Yes, director Michael Bay has said that he's not keen on 3D in earlier reports. However, Variety mentions a possibility for TF3 being done in that format.

Bay's next project is "Transformers 3," and there have been discussions among Bay, Paramount and Industrial Light & Magic about going 3D with the pic. The big stumbling block is the extra time required to do production and visual effects in 3D, as the movie's release date is already set. Having the pic post-converted could alleviate that problem.
